End of story really. If you have AT fitted and you find it's gone up to mid 11's - send it back to be turned down.
If however you have a gun with an external power adjuster that can be easily turned up from low 11's to over 12.. you're putting yourself at risk (although I don't think it's a significant risk)
I am in possession of an AMTA email basically agreeing with you! SO, why were AA S200's sold for so long with the p!ss-easy power adjustment? When I bought mine I assumed that I was buying a product that was legal. Mine is now on ticket!
